Abstract: The stability of carotenoids in citrus peel was analysed with HPLC under the conditions of sunlight, high temperature, acid and oxidants. The carotenoids in citrus peel are easy degenerated by sunlight, high temperature, acid and oxidants. The main degradation mode is to oxidize and break the C=C double bonds of carotenoid. Different isomerization of carotenoids in citrus peel is elicited by sunlight, high temperature and acid.

Key words: HPLC, citrus, carotenoids, stability
